THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 320,817, dated June 23,1885.

Application filed October .25, 1884.

To all whom, it may concern.-

Be it known that I, NEWTON RICHEY, of Ashland, in the county of Ashlandand State of Ohio, have invented a new and useful Improvement inThill-Couplings; and I do hereby declare that the following is a full,clear, and exact description of the same.

My invention is an improvement in thillcouplings of that class in whichthe bolt holding the shaftiron to the socketis held in place by amovable stop, whereby the shaft-iron is held securely against accidentaldisplacement, but is easily removed whenever it is desired to remove theshafts.

The invention consists in details of construc tion hereinafi erdescribed and claimed,the purpose of which is to provide a simpleconstrue tion of easy manufacture, which construction will also furnisha secure hold of the shaftiron and a constant spring'pressure againstsaid iron to prevent rattling.

In the accompanying drawings, Figure 1 is a perspective view ofthcentire coupling. Fig. 2 is a section through the clip-socket andshaftiron and also through the spring-bolt and p ressure-plate. Fig. 3is a section taken longitudinally through the coupling on the line withthe bolt and the pressure-bar.

A clip, A, of ordinary construction, surrounds the aXle. Integral withor connected to this is a socket-piece, B, the sides a a of which extenddownwardly forming downwardly-projecting ear or ears I) 1). Upon thesesides the eye 0 of the shaft-iron fits snugly. Holes in the sides,adapted to register with holes in the eye 0, admit the bolt (1, the headof which is countersunk into the side. In the lower ends'of the ears I)b are holes made directly opposite each other to receive thepressurebolt 0. One end of this bolt is provided with a head or nut, andupon the other end is a stoparm, 9, the arm being fixed to the bolt. Theupper end of this arm is adapted to swing over and close to the outerface of the side I), which is countersunk for the head of the bolt (1.

The upper end of the arm 9 is provided with offsets h, which, when thearm is swung up to cover the head of the bolt d, fits snugly over theupper edge of the side I). This offset is pro vided with a lockingpin,1, on a reduced shank, and within ahole in the offset is a spring, 2.

The upper end of the shank is provided with (No model.)

a head, 3, and the spring tends to force out the pin 1 into a hole, 4,in the upper edge of the side. This pin holds the plate 9 over the endof the bolt d and prevents it from coming out. In order to remove thebolt, the head 3 is lifted and the spring thus withdrawn, when the platemay be sprung before uncovering the countersunk head of the bolt d.

The pressurebolt e is cut away, as shown at 5, on the side opposite thatin which the arm eXtends-that is to say, when the arm covers the boltand is locked in place the rounded side is uppermost and the flat or outside is underneath.

Between the ears I) I) or lower part of the sides b b is apressure-plate, H. This plate has front and rear flanges, 6 and 7 whicheX tend up the edges of the cars, so that the plate rests upon thepressure-bolt and is held against displacement to front or rear by theseflangeextensions, (marked 6.)

A spring, Z, of rubber or equivalent mate rial, is held in theprcssureplate between the flanges and the sides I) b, and a pieceagainst the lower surface of the eye shaftiron.

When it is desired to connectthe shaft to the clip, the arm 9 is throwndown to a vertical dependent position, and the vertical plate rests uponthe cut-away portion of the pressure-bolt, being thereby lowered, andwith it the spring is also lowered. The eye of the shaft-iron is thenintroduced and the bolt d inserted. The arm g is then brought up to itsplace to cover the end of the bolt until the pin is forced into thehole. This turns the pressure-bolt with its rounded side up, raising theplate, and puts the spring under compression.

The bolt is easily made by cutting away air ordinary iron bolt.

The construction of the pressure-plate is such that the spring is heldsecurely, but may be easily removed.

The parts may be all formed cheaply and work securely when in place,

I claim as my invention.
